Adding a second battery...

...So, I'm thinking about dry camping with the Tradewind, and I'm thinking a single battery may not do me for a whole weekend. Aside from buying a whole umpteen zillion dollar generator, how about a second battery?

I saw a tradewinds that had what looked like two batterys stock from the factory, one door on the curb side of the front of the trailer, and the other door on the other side.

Is a retrofit like this possible? Well, let me put that another way, 'cause anythings's possible if you're willing to spend your life savings on it.

What's the best slash cheapeast way to do that? Are the door and boxes available? I'd like it to look as factory as possible...

Adding battery compartments is likely to be an expensive process and you will need to make sure there is room on the inside.

I think a better solution would be to get a couple of AGM type batteries, One to replace the existing battery and another to place inside somewhere convenient to wire in as a bank. The AGM's are a bit more expensive but completely sealed (can be shipped UPS ready to go) and are a bit more rugged than wet cells.

for some ideas on the serial vs parallel consideration as well as some links that might be of interest.

Depending on avail real estate, it is not that hard. If the photos were up, you could see the box Airstream put on the Bambi that they crammed two batts in.

Thumbs up Two Battery Compartments

Two Battery Compartments are a distinct possability; I just had the street side compartment put in by my local AS mechanic; I would not suggest that you try this yourself unless you have a sound grounding(pun intended)! in Automotive Electronics, as the second battery will have to be tied into the univolt. The factory will not sell to ship a battery compartment, you will have to go through an AS dealer, even if you have more knowledge of what you want than the dealer They charged me $350.00 for a battery assay' and it was the wrong one, it took many weeks of arguementation befort the technical staff finally were called in to address the issue; turns out that the parts people did'nt know what they were talking about: The final analysis is that the compartment is installed and functioning perfectly. Your biggest problem is securing the Battery Compartment Assy. for your particular year and model AS, Good Luck!!!
